Phenotypic Shifts in Macrophages Within Advanced Atherosclerotic Plaques in Humans

FASEB BioAdvances, EarlyView.
The transition from a non‐atherosclerotic to an atherosclerotic artery is associated with a shift in macrophage phenotypes. In the homeostatic environment of a non‐atherosclerotic artery, macrophages are predominantly anti‐inflammatory, anti‐atherogenic.

Impact of Surgeon Experience During Carotid Endarterectomy Operation and Effects on Perioperative Outcomes

Brazilian Journal of Cardiovascular Surgery
Objective: We evaluated the effect of surgeon experience on complication and mortality rates of carotid endarterectomy operation. Methods: Fifty-nine consecutive patients who underwent carotid endarterectomy between January 2013 and February 2016 were ...

Association of a State‐Wide Alternative Payment Model for Rural Hospitals With Bypass for Elective Surgeries

Health Services Research, EarlyView.
ABSTRACT Objective This study aimed to measure the changes in rural hospital bypass for 11 common elective surgeries following the implementation of the Pennsylvania Rural Health Model (PARHM), a global budget payment model. Study Setting and Design We leveraged a natural experiment arising from the phase‐in of PHARM in Pennsylvania.

Left acute neovascular glaucoma after right carotid endarterectomy

Journal of Vascular Surgery Cases and Innovative Techniques, 2018
Carotid endarterectomy is a commonly performed vascular surgical procedure with well-known complications, such as stroke and nerve injury. Neovascular glaucoma (NVG) is an exceedingly rare complication after carotid endarterectomy that can result in loss

Surface Metrology of Cerebral Arteries Luminal Surface [PDF]

arXiv, 2023
Atherosclerotic lesions within carotid and cerebral vessels are likely to influence hemodynamics and manifest into vascular pathologies, including Alzheimers Disease and ischemic stroke. Hemodynamics are influenced by changes in luminal diameter of vessels and wall shear stress derived from turbulence, which directly relates to the surface topography ...

Global sensitivity analysis informed model reduction and selection applied to a Valsalva maneuver model [PDF]

, 2020
In this study, we develop a methodology for model reduction and selection informed by global sensitivity analysis (GSA) methods. We apply these techniques to a control model that takes systolic blood pressure and thoracic tissue pressure data as inputs and predicts heart rate in response to the Valsalva maneuver (VM).

Serious outcomes among emergency department patients with presyncope: A systematic review

Academic Emergency Medicine, EarlyView.
Abstract Background Syncope is transient loss of consciousness, and in presyncope, patients experience same prodromal symptoms without losing consciousness. While studies have extensively reported the risk of serious outcome among emergency department (ED) syncope, the outcome for patients with presyncope and their management are not well studied.

Computational Fluid Dynamic Simulations In a Model of a Carotid Bifurcation Under Steady Flow Conditions [PDF]

arXiv, 2020
Strokes are still one of the leading causes for death after heart diseases and cancer in all over the world. Most strokes happen because an artery that carries blood uphill from the heart to the head gets clogged. Most of the time, as with heart attacks, the problem is atherosclerosis, hardening of the arteries, calcified buildup of fatty deposits on ...

Deep Learning-Based Carotid Artery Vessel Wall Segmentation in Black-Blood MRI Using Anatomical Priors [PDF]

arXiv, 2021
Carotid artery vessel wall thickness measurement is an essential step in the monitoring of patients with atherosclerosis. This requires accurate segmentation of the vessel wall, i.e., the region between an artery's lumen and outer wall, in black-blood magnetic resonance (MR) images.
